Definitions

  • the present invention relates to a drive system comprising an inverter, an electrical rotating machine and a control device, the inverter comprising a first input, a second input, N arms connected in parallel between the first input and the second input, N being a natural number greater than or equal to 2, each arm comprising an upper half-arm and a lower half-arm in series, the upper half-arm being connected to the first input, the lower half-arm being connected to the second input, the upper half-arm and the lower half-arm of each arm being connected together at a corresponding output of the inverter, each upper half-arm and each lower half-arm comprising at least one switching module capable of switching between an on state and a off state, each of the first input and the second input being intended to be connected to a respective terminal of a direct current source, each output being associated with a respective electrical phase, the rotating machine comprising a stator and a rotor movable in rotation, relative to the stator, around an axis of rotation, the stator comprising N windings,
  • the invention also relates to a feeding method implemented by such a system, as well as a compression assembly comprising such a system.
  • a conventional method of manufacturing a rotating machine involves attaching already magnetized permanent magnets to a rotor body, with the rotor then being placed in a cavity of a corresponding stator.
  • the rotating machine obtained by such a manufacturing method is not optimal for use in driving a turbomachine, in particular a turbocharger for a vehicle. Indeed, in such an on-board application, the rotating machine is only used occasionally. In this case, when it is not powered, the rotating machine generates a torque resisting rotation, which leads to no-load losses.
  • One aim of the invention is therefore to propose a drive system which is simpler and more economical to produce, while generating fewer losses when the rotating machine it comprises is not in use.
  • variable magnetic flux drive system includes a permanent magnet motor that uses a permanent magnet, an inverter that drives a permanent magnet motor, and a magnetizing means that flows magnetizing currents to control the magnetic flux of the permanent magnet.
  • the permanent magnet is variable, its magnetic flux density being able to vary depending on the magnetizing current from the inverter.
  • the magnetizing means flows the magnetizing current that is equal to or greater than a magnetizing saturation region of the magnetic body of the variable magnet.
  • the rotating machine 8 is intended to drive in rotation an element connected to its output shaft, in particular a fluid compression device, for example a compressor or a turbocharger.
  • a fluid compression device for example a compressor or a turbocharger.
  • the rotating machine 8 comprises a stator 30 and a rotor 32 movable in rotation, relative to the stator 30, around an axis of rotation XX.
  • the stator 3 comprises N windings 38, arranged in a known manner to generate a magnetic field in the cavity 34 when an electric current passes through them.
  • the windings 38 are arranged so that the magnetic fields corresponding to two separate windings 38 are images of each other by a rotation of a non-zero angle multiple of 360°/N.
  • Such a material is, for example, an alloy called FeCrCo comprising iron, chromium and cobalt, or an alloy called AlNiCo comprising aluminium, nickel and cobalt.
  • the rotor 32 advantageously comprises a plurality of magnetic elements 48 arranged circumferentially around the axis of rotation X-X, preferably at regular angular intervals.
  • k is N-m, i.e. there is no inactive arm during the magnetization step.
  • the m current injection arms and the k current output arms are, for example, predetermined.
  • the electric current from the source 4 is routed to the first input 14, then, through the upper half-arms 20 of the m current injection arms, to the windings 38 connected to said current injection arms.
  • the current then reaches the common point 44, then flows in the opposite direction, i.e. from the common point 44 to the outside of the rotating machine 8, through the k other windings 38 connected to the current output arms.
  • the current is routed to the second input 16 through the lower half-arms 21 of said current output arms.
  • the switching modules 26 of the N-m-k other arms 18 being in the off state, no current flows through the windings connected to them.
  • the path of the electric current described above corresponds to the situation where the first input 14 is brought to a higher electric potential than the second input 16. In the opposite situation, the electric current follows the opposite path.
  • the windings 38 are arranged to generate magnetic fields in different directions. Furthermore, for a given winding 38, the direction of the magnetic field generated by said winding depends on the direction of the electric current flowing through it (i.e., from its input 40 to the common point 44, or from the common point 44 to its input 40). As a result, the amplitude (as well as the direction and sense) of the total magnetic field in the cavity 34 varies depending on which arms 18 act as current injection arms and which act as current output arms. Consequently, the minimum duration allowing magnetization of each magnetic element 48, i.e., the minimum duration of the magnetization time interval, varies depending on the chosen combination of current injection arms and current output arms.
  • the duration of the magnetization time interval is also chosen as a function of the material with modulatable magnetization from which each magnetic element 48 is made.
  • the magnetization time interval corresponds to the time interval during which each magnetic element 48 is subjected, during the magnetization step, to the magnetic field intended to cause its magnetization.
  • the duration of the magnetization time interval is chosen to ensure magnetization of each magnetic element 48.
  • the rotating machine 8 is a three-phase machine.
  • the number m is chosen equal to 1, and the number k chosen equal to 2.
  • the path of the electric current is illustrated by dotted arrows.
  • the control device 12 controls the inverter 6 so that, for the single current injection arm, the switching module 26 of the corresponding upper half-arm 20 is in the on state, and the switching module 26 of the corresponding lower half-arm 21 is in the off state.
  • the winding, denoted 38A connected to the output 22 of the current injection arm, is crossed by the electric current delivered by the source 4 in a direction going from the first input 14 of the inverter to the common point 44 of the rotating machine 8.
  • the stator 30 comprises a single pole per winding 38. However, a higher number of poles per winding 38 is possible.
  • control device 12 is advantageously configured to implement the magnetization step prior to a step of excitation of the rotating machine 6.
  • Such an excitation step comprises the control of the inverter 6 so as to inject, into the windings 38 of the stator 30, electric current to generate, in the cavity 34, a magnetic excitation field intended to drive the rotation of the rotor 32 around the axis of rotation X-X.
  • control device 12 is configured to, during the excitation step, control the inverter 6 according to a predetermined inverter control law to connect, successively over time, the first input 14 and the second input 16 of the inverter 6 to each of the outputs 22 of the inverter 6.
  • the first switching member 50 is connected in series between each arm 18 and the second input 16 of the inverter 6. Furthermore, the second switching member 52 and the load 54 are connected in series, and connected in parallel with the first switching member 50.
  • Each of the first switching member 50 and the second switching member 52 is capable of switching between a blocked state preventing the flow of electric current, and an on state allowing the flow of an electric current.
  • Each switching member 50, 52 is, for example, a MOSFET transistor or a relay.
  • control device 12 is advantageously configured to, during the magnetization step, simultaneously control the first switching member 50 so that it is in the blocked state, and the second switching member 52 so that it is in the on state.
  • the load 54 is inserted into the circuit through which the electric current flows between the first input 14 and the second input 16, so that the intensity of the current flowing in the windings 38 during the magnetization step is also a function of the impedance of the load 50.
  • the magnetic elements 48 of the rotor 32 have no magnetization, and the rotor 32 is arranged in the cavity 34 of the stator 30.
  • the input 40 of each winding 38 of the stator 30 is connected to a corresponding output 22 of the inverter 6.
  • each of the first input 14 and the second input 16 of the inverter 6 is connected to a respective terminal of the direct current source 4.
  • the control device 12 controls the inverter 6 according to a predetermined inverter control law (control by pulse width modulation, for example) to connect, successively over time, the first input 14 and the second input 16 of the inverter 6 to each of the outputs 22 of the inverter so as to inject excitation currents into each of the windings 38 of the stator 30 in order to generate, in the cavity 34 of the stator 30, a rotating magnetic field intended to drive the rotor 32 in rotation around the axis of rotation X-X.
  • a predetermined inverter control law control by pulse width modulation, for example
  • Such a characteristic is advantageous, since a judicious choice of the magnetization outputs leads to the generation, by means of the stator, of a magnetic field intended to modulate, in particular to reduce, or even to cancel, the magnetization of the magnetic elements 48. This has the effect of reducing the losses due to the rotating machine 8 when said rotating machine 8 is no longer required for driving, compared to a situation where such modulation of the magnetization of the magnetic elements would not be implemented.
